석유 등의 화석연료가 연소되면서 발생하는 이산화탄소를 주체로 하는 ''온실효과가스''의 배출량이 점점 더 증가해 감에 따라 지구온난화가 국제적으로도 커다란 환경문제가 되고 있다. 이산화탄소의 배출을 억제하기 위한 구체적인 시책은 바로 자에너지(에너지 절약/ 이용합리화)의 수행이다. 이번에 자에너지를 주목적으로, ISO14001의 환경매니지먼트 모델을 전체적으로 지원하는 공장에너지관리시스템과 조명$\cdot$빌딩분야에서 환경매니지먼트 모델을 지원하는 조명제어시스템 및 빌딩 설비 감시시스템을 구축하였다. 신규개발한 Controller의 소프트웨어는 24시간 가동가능한 OS(Operating System)에 제어미들웨어를 탑재하여 Object설계방법으로 제작된 기능별 어플리케이션 소프트웨어를 각 시스템별로 조합한다. 하드웨어는 퍼스컴과 동일한 DOS/V머신 구성으로 하여 시스템의 주체가 되는 부송부의 하드웨어를 개발하였다. 구축한 각 시스템의 내용은 다음과 같다. (1)공장에너지관리시스템 수집한 에너지사용량 데이터를 관리$\cdot$분석용으로 가공하는 생에너지 지원용 어플리케이션 소프트웨어를 탑재하고있어 환경매니지먼트 시스템(ISO14001)을 실행하는 데에도 유용하다. (2)조명제어시스템 지금까지 단독기기였던 조도일정제어의 조광컨트롤러에 B/NET 전송기능을 탑재하여 스케줄 및 디맨드 감시에 의한 조광제어를 시행하여 한층 더 생에너지를 실현한다. (3)빌딩설비 감시시스템 빌딩의 에너지관리, 조명$\cdot$공조제어에 의한 생에너지화, 보전업무의 효율화$\cdot$생력화를 실현한다.

정보통신 기술의 발전으로 교육 패러다임이 스마트 디바이스를 이용하는 스마트 러닝으로 변화하고 있다. 특히 에듀테인먼트 시스템들은 암묵적 지식습득률 향상을 위하여 증강현실 기술을 도입한 다양한 시스템들이 도입되고 있다. 그러나 이와 같이 증강현실을 이용한 시스템들은 실환경의 조명과 가상환경의 조명환경의 부조화로 인하여 영상 합성시 실감성이 낮은 문제점을 가지고 있다. 따라서 본 논문에서는 증강 객체, 웹캠을 통해 입력된 영상, 가상의 배경 영역으로 구성된 단일 레이어를 3차원 조명환경 정보를 포함한 블록 레이어로 변환하고 변환된 블록 레이어를 합성하는 에듀테인먼트를 위한 증강현실 시스템을 설계한다.

In this paper, we propose an efficient hybrid lighting management system implementation on multiple protocol. The proposed hybrid lighting management system was implemented by configured as the data display part for management and control of lighting device and the data conversion-processing part the communication part of gateway. The data were designed the DB to enable to storage in real-time, and implemented able to manage by real time wireless remote control and schedule setting. The proposed an efficient hybrid lighting management system, it was possible the real-time monitoring and remote lighting control by peristalsis with smart devices and portable PC etc., and it could be obtained reduction effect of energy and electricity, communication cost.

Recently, the problem of global warming has issued seriously, so Green IT(Information Technology) using RFID/USN is concerned in order to solve environmental problems. In this paper, we implemented that public area like an underground parking lot could reduce unnecessary energy consumption used by lighting control system based on Ubiquitous Sensor Networks. The lighting control system for underground parking lot is comprised of intersection nodes for watching cars enter and leave, and light node for controlling light. It applies the routing protocol based on hierarchical cluster, hierarchical addressing method, and probability filtering method for the specific place like an underground parking lot. The result after experiments shows that the lighting control system could decrease electrical energy consumption to around 61.7%.

This paper describes a study on the intelligent LED lighting system implementation applicated environmental reservation setting. The environment variables are preset by ON and OFF time of illuminator and brightness data. The setting data enables to be changed by personal preferences on the selecting menu. It is possible to reduce unnecessary consumption and operation for the lighting system. The system customized by user's environment is convenient for disability by using bluetooth. Thus the system results in cost effective and energy savings. The system performances are examined for convenient operation and energy saving for practicality in implemented system.

This paper proposes color segmentation for detecting missing persons in a smart lighting system using radar and camera sensors. Recently, smart lighting systems built-in radar and cameras have been efficient in saving energy and searching for missing persons, simultaneously. In smart lighting systems, radar detects moving objects and then the lights turn on and camera records. The video recorded is useful to find out missing persons. The color of their clothes worn in missing persons is one of critical hints to look for missing persons. Therefore, color segmentation is an effective means for detecting the color of their clothes. In this paper, during the color segmentation step, the ROI(Region of interest) setting based on the size of an object is applied and the background is reduced. According to experimental results, the color segmentation has good accuracy of more than 97%.

When lighting has installed indoor, we control lighting using human-detecting sensors for people who pass at night and places that are lack of quantity of light. However, malfunction can be caused by positions of inappropriate sensors, and in the case of passages of big buildings, it is a problem that even after a person pass, light apparatuses are turned on for a long time. In this paper, we propose lighting control system based on location positioning for energy saving that control lighting in accordance with passers's position through indoor location positioning. This system use the fingerprinting technology that is one of the location positioning technologies and RSSI data that is collected by a smart device. Using those, it can turn on only lightings that are included in the positioned location and reduce unnecessary power consumption. As a result of experiment, on condition that four people were existing and illumination was 308 lux, we assured reduction effect of 49 Wh.
